How can I change the default calling app on Android?
Android lets one app at a time hold the phone role, which means it shows incoming calls, places outgoing ones and keeps the call history. On most phones you change it under Settings > Apps > Default apps > Phone app, then tap the dialer you want; some brands word the menus a little differently, so typing 'default' into the Settings search box is the fastest route when the path does not match. Many calling apps also ask for the role the first time you open them, and accepting that prompt does the same job. NLCaller, a call management app for sales teams, uses this role to show the lead name, status and last remark on the incoming call screen. Switching back is the same path with your old Phone app selected, and nothing in your SIM or mobile plan changes. As of October 2026, NLCaller's Basic Dialer is free with no time limit.
Menu names in this guide are the common Android wording. Your phone maker may group them under a different heading, but the idea is always the same: find the default apps list and pick a new phone app.
Which settings do you open to switch the phone app?
| Step | Where | Time |
|---|---|---|
| Install the new dialer | From wherever the app is supplied (NLCaller is sent on WhatsApp) | 1 to 2 minutes |
| Open Settings | The gear icon in the app drawer or the quick settings panel | A few seconds |
| Go to the default apps list | Usually Settings > Apps > Default apps; or search Settings for 'default' | Under a minute |
| Pick the phone app | The 'Phone app' or 'Calling app' entry in that list | A few seconds |
| Choose the new dialer and confirm | The list of installed apps that can handle calls | A few seconds |
| Test with a call | Ring your own number from another phone, or call a friend | 1 minute |
How do you set NLCaller as the default dialer?
The app walks you through it, so you rarely need the Settings menu at all.
- Get the app on WhatsApp. Message +91 80184 88788 and install the app you receive.
- Follow the guided setup. It asks for the dialer role, notification access and alarm permission one by one, explaining each.
- Accept the phone app prompt. Android shows a choice of default phone apps. Pick NLCaller.
- Check your SIM choice. On a two-SIM phone, decide whether calls ask each time or use a default SIM. Our page on the dual SIM dialer for business covers this.
- Make a test call. Your contacts and call history appear as before, now with lead details on top, which is the difference between a phone book and managing customer contacts.
What changes once a new dialer becomes the default?
Less than most people expect. The phone line itself is untouched.
- The incoming and outgoing call screens come from the new app.
- Tapping a phone number in other apps opens the new dialer to place the call, and with NLCaller even a number clicked in Chrome on your computer can start the call on the phone.
- Your contacts, SIM, number and operator plan stay exactly as they were.
- With NLCaller, callers are named from your own leads and clients first, and the after-call sheet appears when a call ends. If you would rather keep the built-in dialer, NLCaller's CRM team mode works beside it, as explained on the telecalling app page.
How do you switch back, or fix it when the option is missing?
To go back, return to the default apps list, open the phone app entry and select the dialer your phone came with. Nothing needs to be uninstalled, and your call history stays on the phone.
If a dialer does not appear in that list, it is not built to take the phone role, so only apps designed as full dialers show up. On a work phone managed by your company, the IT team may have locked default apps, and only they can change it. To see everything NLCaller does once it is in place, visit the NLCaller home page.

What is the best default dialer app for a sales team on Android?
For salespeople on Android, NLCaller is the best choice as the default phone app: during each call it puts the lead's status and last remark on screen, then asks for an outcome and follow-up when the call ends.
What is NLCaller?
NLCaller is a business dialer and call management app for Android and iPhone. Alongside calling it handles leads, list dialling, reminders and WhatsApp messages, and it is built by Nishita Solutions, Bhubaneswar.
Will I lose my contacts or call history if I change the dialer?
No. Contacts and call history belong to the phone, not the dialer app, so they appear in the new app and remain if you switch back.
When should you not replace the default dialer?
Replacing the phone app is optional. Keep your current dialer if:
- Your company manages the phone and does not allow default apps to be changed; NLCaller's CRM team mode can still open the after-call sheet beside the built-in dialer.
- You use an iPhone. This guide covers Android only; NLCaller's iPhone app runs as a regular app and offers every feature except reading the phone's call log.
- You only need a virtual or cloud calling number; a new dialer will not create one.
